seatpost shim

[twain]

i have a USE shock seatpost 26.8mm. my Specialized hardrock comp i think takes a seatpost at 30.9
i cant seem to find a shim that will help me convert....
not even sure it exists. is there another way round this as i want to keep the seatpost.....??

hmmm. I can only find 27.2->30.9 here http://www.wiggle.co.uk/p/cycle/7/Cane_ ... 300003046/ and here http://www.wiggle.co.uk/p/cycle/7/Post_ ... 110000412/

Could you use a coke can shim to go from 26.8->27.2 then one of these shims? Not ideal I'll concede...

hold everything. How about 26.8->31.0

Wonder if there is any way you can step down using 2 shims?

ta, but im gonna give the 31.0 shim a try, 0.1 of a mm should be easy enough to shave off if needs be....(thanks orange71)

coca-coal cans are 0.1 mm, I know that coz I've been making little red shims for disc brake calipers.

I've got a b'twin 23.4mm seatpost from France, for a Pug bike with 24mm seattube, the shims that came with it are too big, what would people recommend? Lots of drinks cans?

Bugger, wrong forum, I need to get to grips with the search function better.
